Endothall violations in Pennsylvania

196 active public water systems in Pennsylvania had a Endothall violation in the past three years, 8 of them in the latest quarter of EPA's data. What Endothall is and why it matters.

Health effects: Short-term exposure above the MCL can cause gastrointestinal irritation and stomach cramps. Chronic exposure is associated with liver, kidney, and gastrointestinal damage in animal studies. EPA has not classified endothall as a human carcinogen. The general population is at risk from water system violations.

About this data

A system is counted once if any of its violations in the past three years involved Endothall, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Endothall alone.

Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The Pennsylvania records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
